BIOS is being Spazztic

I don't really know where to put this so I'm putting it here for now.

 

So every time (except the first two times) I start up my computer, my BIOS screen flickers and has graphical errors every where. I'm not sure what causes this because I would like to have a peek in my bios to see if I can OC my ram because it's at 1600mhz, when it's supposed to be running at 1866. I don't really know why but the whole computer remains functional.

 

Can someone explain and maybe have an idea how to fix it?

It happens on the main screen and in the bios. The same type of graphical error too.

update the bios.?

corrupted bios, please try updating it or overwriting it with the same version (if it's the latest)
